Yeah. If you just want HDR, Cable Matters is the way to go.
If you buy one and flash it with a sketchy firmware, you can get VRR. But my understanding is the HDR is a smaller range. How much that matters when the vast majority of games aren’t taking advantage of HDR is up to you.
Personally? I love how much HDR pops. I more or less need VRR to not have to care about frame tearing and the like. And when I am running games on an underpowered glorified AMD NUC (or, in my case, ACTUALLY an AMD NUC)… my framerates are neither high nor stable.






I’m explicitly not going to link to it as I can’t personally vet how safe it is or its origins but:
No. Check the various issues related to the subject matter. And hobbyist threads on sites like resetera.
